The 4” VEX mecanum wheels strafed three Sack Attack sacks (that is, 15.5”). That’s about 6:5 strafing distance to wheel circumference. More tests were necessary to make sure that ratio exists on the FRC robot as well.

We have decided to have a bar going from the top of the front tower to the back of the side rails to provide more structure. We have also decided to have two arms for the intake because earlier, the ball would not properly get through. Also we changed to having the two intake wheels by about six inches to allow more surface area on the ball.

We’ve done more work on the low goal: mounting hinges and connecting sides to each other. We’ve had a bit of trouble figuring out how the sides fit together, however.

We’ve discussed various ways of winding up and releasing the catapult: besides the Choo-choo design, Christian started prototyping a design involving two worm motors and a pneumatic. This transmission is a two speed with worm drive that engages with pneumatics.

Classmate was configured and connected. The control system is now working, sans joysticks. We were able to receive video from the axis on the classmate and power a motor in autonomous.
